CAUTION
The dynamic brakes must be used only on errors that cause the forced stop, emergency
stop, or servo OFF. These brakes must not be used for normal braking.
The brakes (electromagnetic brakes) assembled into the servo motor are for holding
applications, and must not be used for normal braking.
The system must have a mechanical allowance so that the machine itself can stop even if
the stroke limits switch is passed through at the max. speed.
Use wires and cables that have a wire diameter, heat resistance and bending resistance
compatible with the system.
Use wires and cables within the length of the range described in the instruction manual.
The ratings and characteristics of the parts (other than Motion controller, servo amplifier
and servo motor) used in a system must be compatible with the Motion controller, servo
amplifier and servo motor.
Install a cover on the shaft so that the rotary parts of the servo motor are not touched
during operation.
There may be some cases where holding by the electromagnetic brakes is not possible
due to the life or mechanical structure (when the ball screw and servo motor are
connected with a timing belt, etc.). Install a stopping device to ensure safety on the
machine side.
CAUTION
To maintain the security (confidentiality, integrity, and availability) of the programmable
controller and the system against unauthorized access, denial-of-service (DoS) attacks,
computer viruses, and other cyberattacks from external devices via the network, take
appropriate measures such as firewalls, virtual private networks (VPNs), and antivirus
solutions.
